You spend half of your money on a movie ticket. Then you spend half of what you have left to buy a large popcorn. Then you spend half of what remains to buy a small drink. Which expression equals the fraction of money you have left?

Spent half on movie tickets:

Movie Tickets = 1/2

Remaining = 1 - 1/2 = 1/2

Spent half of remaining on popcorn:

Popcorn = 1/2 of 1/2

Popcorn = 1/2 x 1/2

Popcorn = 1/4

Remaining = 1/2 - 1/4 = 1/4

Spent half on remaining on small drink:

Drink = 1/2 of 1/4

Drink = 1/2 x 1/4

Drink = 1/8

Left:

1/4 - 1/8 = 2/8 - 1/8 = 1/8

Ans: 1/8 of the money is left.
